Re: Forget the politicians

"In the case of the US, are you confusing visas with their electronic travel authorisation system for visa free travel? In most cases a "visa" still means sending off your passport and getting a visa put in it."

No, there is such a thing as an electronic visa that combines the ESTA mechanism with visa issuance. It involves an online registration, uploading your passport bio page and a picture in scanned form, and paying a fee. You get your approval or denial by email and you print the approval notice and carry it with you.

India has updated its immigration systems to process pretty much the entire world this way, for tourism and medical visitors. You no longer send out a passport anywhere. That's only done for longer and more specialized visit types, that don't apply to the vast majority of the visitors.

Re: Fgs

"The Commonwealth doesn't have one, India has one.

If you ask nicely and permit increased immigration they might let you join in... but it is a regional system with coverage of the area containing targets for their nuclear missiles."

The current IRNSS system is indeed regional. It was conceptualized after GPS access issues during the 1999 Kargil War. Budget allocations started 2006, and satellite launches started in 2013.

It became operational in Spring 2018 with the launch of the 7th satellite IRNSS-1I in April, and covers India along with an area extending 1500km around it. The total cost so far is approx $340 million for the project, 7 sats and launchers (PSLV-XL).

It will be expanded to a global network of 24 satellites, probably by the mid 2020s.

Re: Fgs

It has ‘limited geographical coverage’ because it’s not a commonwealth or global system by design . IRNSS is the Indian Regional Navigational Satellite System. Like the Chinese Beidou system, it’s India’s homegrown navigational satellite system, created after the US blocked access to accurate GPS signal in the past, leading them to decide the only way forward was a homegrown system .

Tesla undecimates its workforce but Elon insists everything's absolutely fine

Raj

I’m glad you acknowledge the impact of your own constraints on carbuying choice . Too many criticisms of EVs related to inability to home charge, conflate the persons own constraints with that of the car .

A contractor or foreman clearly shouldn’t buy a Kia Rio or Toyota Yaris, and then complain it can’t handle the piles of lumber he tried to stick inside at Home Depot . Similarly, it isn’t the smart choice to buy an EV if you’re clearly constrained from easily charging it .

However, when you live/work someplace where the charging infrastructure works for you, at least with a Tesla and it’s network of chargers, I find practically no compromise . Quite the opposite, since my energy and overall operational costs are way lower .

Your post is factually wrong. Is also is extremely short sighted, and apparently that of a person who hasn’t used the car he’s talking about, at any length . And yes, I know - I drive a Model S.

It doesn’t take ‘hours to supercharge a Tesla’ . The time to gain a functional charge is counted in *minutes* . You can go from 20% to over 80% charge in under 30 minutes . Over 90% in between 30-45 minutes . Beyond that, charge rate tapers .

BUT - charging 100% is usually pointless . Regen braking is turned off due to high charge level, so you don’t gain what it would otherwise offer . Superchargers in most urban areas with lots of Tesla’s are 50mi apart or less.

Another gaping hole almost every non EV owner discounts - because they’ve never experienced its worth - is that having a plug in the garage means you wake up every morning to a full tank . And no, it doesn’t take 10-12hrs . A NEMA 14-50 pushing a sustained 40A gets you an approx 30 miles/hr charge rate . My 75D is typically done in 5-6hrs, using the ToU rate starting midnight , with anywhere from 10-20% initial charge and 90% limit setting .

And the 255mi range ? That is not the range you get by babying the car . Rather, it’s what you get when you do 70-75mph on the freeway . If you putter along at 35-45mph around town, you’ll get a higher range than advertised : https://insideevs.com/heres-how-speed-impacts-range-of-the-tesla-model-s/

I’ve driven mine two years now . Well north of 50K miles in those years . My round trip commute is almost 200 miles, and I can do it on one charge . I’ve driven up to the Canadian border and back from LA . It just works . Supercharging plus destination chargers meant I woke up more than once with a full tank in the car .

Range anxiety is a normal thing for those who aren’t familiar, or even EV newcomers . Most other EVs are not yet functional , but Tesla’s are . The supercharger network is a force multiplier that no one else has, as yet .

Tesla launches electric truck it guarantees won't break for a million miles

Raj

Re: Tesla semi?

I’ve owned a Model S for two years and have covered over 40K miles, and that comment is nonsense . I get within 100-102% of rated range doing 70-75mph on the freeway with the climate control running . Under extremely inclement conditions - heavy rain and wind - I still manage within 110-115% . Under 55mph I get above rated range performance . There’s absolutely no ‘feathering’ involved . Quite the opposite in fact , considering the instantaneous torque on tap.

'Fat boy' flies: ISRO's heavy rocket fails to blow up

Raj

Re: And the UK gives "aid" to this country.

The US and USSR came far closer to nuclear war than India and Pakistan ever did. Even today, Putin and Russia are demonized by the west an order of magnitude more than any heat in the subcontinent.

It's trite nonsense that developing countries cannot establish proper protocols. What's more, China's increasing influence over a progressively deteriorating Pakistani economy ensures that they are less likely to lash out.

As for India, we're a status quo power who simply do not look at Pakistan as a peer. We stopped doing that in 1971 after we cut them in half. Until then, they were quite a large entity, surrounding us from both sides, but Indira Gandhi did generations of Indians a great favour by fixing that problem.

Today they are just a nuisance, falling further and further behind us. At one time, they were quite a bit wealthier than us on average, but are now poorer and falling further behind each passing year. Just India's federal budget alone is already quite larger than Pakistan's entire GDP, and pretty much every other metric is 10-20x larger.

Re: "CE7.5 that sits atop the GSLV is a 75kN staged combustion engine. "

The CE7.5 is a restartable engine.

ISRO is moving to a United Launch Vehicles paradigm, with a TSTO approach using LOX/RP1 plus SRBs for the first stage and LOX/LH2 upper stage. With multiple scalable SRBs and upper stages, they can eliminate the 4-stage PSLV and 3-stage GSLV designs, which both have design tradeoffs they have to stomach.

It's not really a 'mistake' they made as such - they're a very small organization with a tiny budget simply reusing technology as much as they could. They have certain core competencies - great SRBs, a reliable (but hypergolic) liquid engine, and now two good LOX/LH2 motors. For example, the LVM3 has two expanded PSLV first stages as the SRBs, and the GSLV Vikas motor as the main motor.

ISRO doesn't want to play with UDMH/N2O2 any longer. They're instead building the SCE2000 LOX/RP1 motor, which will give them the added benefit of scaling up LVM3 payload to 6+ tons to GTO from the current 5ish.

Re: And the UK gives "aid" to this country.

Pakistan ? India's strategic nuclear program has ALWAYS focused on the People's Republic of China! We tested nuclear weapons within a decade of China, and a full quarter of a century before Pakistan. People overestimate the distance to important Pakistani targets. Many are within mere artillery reach. Most of India's ICBMs/IRBMs fired towards Pakistan will instead land in the vicinity of Turkey or Finland.

Pakistan is not a rival or even a peer to India. They are a small country of nuisance value. China is a rival.

Re: It still isn't a heavy lifter

Several things will change:

* Both the SRBs and the cryogenic upper stage overperformed, based on ISRO's statements.

* Only the 200kN cryogenic stage is completely new. The main stage is the same 2x Vikas from GSLV. The boosters are scaled up version of the first stage of PSLV.

* The Vikas engines will be replaced by ISRO's SCE2000 LOX/RP1 core engine that's in development. They project the payload improving to 6 tons to GTO / 12 tons to LEO, from the current 5 and 10.

ISRO is a very lean organization running on a $1 billion budget. As with PSLV and GSLV, they'll simply iteratively improve an initial design until it's well in excess of original stated capability.

Re: "But under the pressure from the US government the Russians pulled out "

ISRO has now built not one but two LOH/LH2 motors on its own. The CE7.5 that sits atop the GSLV is a 75kN staged combustion engine. The CE20 that sits atop this LVM3 is a 200kN gas generator based design, and currently the most powerful LOX/LH2 upper stage in operation.

India sets June 5 as the day it will join the heavy-lift rocket club

Raj

Re: Labelling

They don't *need* to be sophisticated. They just need to be cheap and reliable. The payload to orbit may be lower than the current Ariane 5, but they *cost* per kg-to-orbit is going to be a very competitive proposition they'll offer. What's more, the LVM3 will scale up to 6+ tons to GTO once they swap the lower Vikas engines with their new LOX/RP1 one.

ISRO today has a roughly $1 billion budget. It used to be about half that, or less. Their design sophistication is imposed by costs - they simply reused a set of basic competencies built up from prior designs. Once they have their new LOX/RP1 engine running, they'll entirely ditch hypergolic fuels and switch to a TSTO approach using LOX/RP1 plus SRB lower stage with either of their two new LOX/LH2 engines for the upper stage.

Re: Do you get what you pay for?

The MAVEN payload is about 50kgs. Mangalyaan's payload is about 16-18kgs. Yes, MOM is more lightweight, but it carries a decent payload, and performed a very elaborate process of getting there, using the Oberth effect to generate enough velocity to get into Mars transfer orbit (despite a couple of motor firing glitches) and subsequently make a very precise Mars orbit insertion on first attempt. Usually the second step doomed many Mars missions.

MOM: CHEAP Mars ship got it right first time. Nice one, India

Raj

Re: 1st time out with a significant science payload is *very* impressive.

We didn't really get a chance to learn much more than that many of them failed many times. The ISRO was under international sanctions until 3 years ago, which meant zero collaboration. They did this all by themselves.

Since the PSLV wasn't capable of lofting the payload with as much force as the MAVEN was by its launcher, they used the Oberth effect to generate the necessary momentum. There was not much margin for error - they needed to calculate the necessary fuel to do the Oberth rings, get catapulted to transfer orbit, and then have enough fuel to capture Mars orbit.

Despite a couple of early glitches, they still arrived in Mars orbit with twice the fuel originally calculated, which means the mission will be much longer than planned.

Our MOM's LATEST EGGS: 'Looking GOOD', chuckle Indian space boffins

Re: Well done India

Patent falsehood. India - effectively the entire expanse of the current state - has been a single political entity several times before the British, the first time being ~2000 years before Chaucer.

Britain itself did not exist until the 18th century, and in fact, had been fighting over what constituted the UK until well into the 20th century, until the Irish split. You guys didn't unite anything - you weren't even a fixed entity yourself. Even Italy and Germany did not exist until the late 19th century.

The concept of a nation state is a very recent one, the very idea of which dates to the Peace of Munster in the mid 17th century. It is Europe that has always seen constant flux

Historically, India has always been treated a distinct civilization that has been ruled by a sequence of dynasties with records dating back more than 2500 years. The Maurya Dynasty, which preceded the first Chinese Qin dynasty, or for that matter, Alexander 'the Great', encompassed a territory comparable to the greatest expanse of British India.

Re: Well done India

The arrangement seems to be working out quite well. The UK sends India money, but has no say in how it is used, ever since 1947. India effectively treats it as reparations for colonial plunder, and proceeds to use it however it decides is best - including sending up satellites, moon and Mars probes. The UK whines, and then sends even more money.

As Borat would say, Great Success!

Mixed bag of motors lifts India's budget Mars shot

Re: But...

This is British local poltiics. The ISRO has been around since the late 1960s. The INCOSPAR existed before that. It sounds like Brits suddenly woke up and went 'ZOMG! We've been sending money there for decades and they've been launching rockets!'

Here's the reality. Britain has no control over what India does with its money. That's been true since 1947. You can stop the peanuts you send as aid if you want, but you've shown no ability to get your political process together to do so. While you continue to send the money over, we'll continue to treat it as reparations for colonial plunder and use it as our own interests dictate.

On my part, the pleasure of being able to peruse the amount of angst in the Brit press, alone is well worth the money spent on this project.
