LEGS IN 2015: SpaceX Falcon's landing PUT ON HOLD

Beachrider

Hot fire test failure...

It is good that SpaceX does this test. Not so good that there are problems with the results. With Orbital now turning over some launches to ULA Titan, this commercial launching shows that this is not yet an activity to take-for-granted.

How does the US government run the internet? This is how

USA running the Internet...

There is nothing preventing others from doing their own services deployment and connecting it to the Internet. There is a lot of evidence that indicates that it is often done. If you follow protocol, no one will notice AND you can inter route packets.

NASA prods sleeping New Horizons spacecraft: Wakey, wakey, Pluto's calling

Beachrider

PLUTO is far from unique...

The issue is that there are MANY bodies expected in orbits like Pluto's. It has a 3:2 ratio of orbital period with Neptune and waggles 17degrees away from the ecliptic. Many others have already been found (Makemake, Vatuna, Quaoar, etc.) that will never collide with Pluto and can coexist indefinitely because of orbital resonances/inclinations.

Pluto was found WAAAY earlier, but it appears to be an example of a class of objects in that general area past Neptune (Kuiper Belt).

Orion: To Mars, the Moon and beyond... but first, a TEST FLIGHT through Van Allen belt

Beachrider

Re: USA commitment to ISS

POTUS is the executive leader of this USA, simple. Commercial space is depending on business until 2024, simple.

Of the 27 'major units' of the ISS, NASA paid for 20 to be made. They were made in various places, though.

Re: Competing with Soyuz...

NASA doesn't appear to agree, perhaps you know more...

NASA wants to 'sleep' the people within Orion for the trip. The CSM and other transit device would give supplies and issue-response mechanisms, as needed.

Nothing wrong with using a separate craft when Mars orbit is achieved, though.

Orion and the ISS...

@bleu, Orion was never scrapped (hence, your word 'nearly'), but its Constellation-project SRB-based rocket system was formally scrapped after the Ares I-x test flight in late October 2009. The Ares V was formally scrapped at the same time.

The direction was changed to focus on commercial vehicles to the ISS.

From that point forward, Lockheed's Orion was for deepspace-only. Boeing presented CST-100 to function at a lower price (and hold more people) than Orion.

Competing with Soyuz...

Remember that CST-100 and Dragon compete with Soyuz, not Orion. The Orion specification is to protect astronauts for many MONTHS outside the Van Allen Belts. Soyuz would need to transfer its load to a more-heavily shielded transit device for the bulk of the trip.

NASA would add the ESA Thales ATV-adaptation plus a Bigelow unit for the longer Martian trip. They are researching keeping most/all of the astronauts 'asleep' for the trip, to minimize the need for highly shielded transport.

NASA is about Basic Research...

NASA's job is to enable basic research on not-yet-commercializable technology areas. The pursuit of commercial space is a key benefit of that research. Even the commercial companies benefited from access to NASA's research (Merlin clearly derived from Fastrac, for example).

There is no commercial model for deepspace manned transfer yet. NASA clearly does not believe that simply adding existing shielding to Dragon or CST-100 will make them into an Orion. We will see.

NASA does need to compete with ESA, RSA, JSA and CSA, as part of the technology-race that is always happening...

USA commitment to ISS

On January 8, 2014, as part of justification to continue Commercial Flights to the ISS, the President commited the USA to support the ISS until 2024. It was in all the papers, 11 months ago.

I don't know why anyone would advise anything else.

BIG FAT Lies: Porky Pies about obesity

Beachrider

Smoking related illness...

I agree with the @AC, stats from the USA indicate that you need to add CHF (Heart Failure) and blood-plaque problems (Kidney Disease, stroke, more) with long-term smoking.

The major stat in the USA is that a person uses 60% of their LIFETIME medical costs in the last six months of life, when a multi-week hospital stay is involved.

SCREW YOU, Russia! NASA lobs $6.8bn at Boeing AND SpaceX to run space station taxis

Boeing is looking at alternatives for Atlas...

Boeing is advising that BE-4 KeraLOX and other engines can be adapted to a new rocket. They are looking at 5 years before it clears all testing. There is NOTHING stopping Boeing from requesting Falcon 9s for their work, though.

The Atlas Vs used in the proposal are about $100 Mn per launch (plus other payload and capsule). Falcon 9s are supposed to be available for under $70 Mn per launch.

Astronaut training, recovery and flight operations are all on the commercial vendor, and in their proposal.

Russian engines on Atlas...

Clearly, having a backlog of 2 years-of-engines within the USA is part of a plan to sustain launches with short-term-stoppages of deliveries. Boeing is working on 'Atlas 6', with some more details by October 1.

Russia advises that they are NOT continuing with ISS past 2020.

The USA has floated a proposal to extend the ISS to 2024. It is not 'pumpkin-time' for Russia's decision YET, but they have advised that they would decline to continue participation past 2020.

Atlas is a brand, not a technology..

Atlas V is a substantially different config than 'earlier' Atlas rockets. It was built to use twin-RD-180 engines for moderate-heavy payloads. Its ancestry is clearly to RD-170 not any American Engine.

Agena had a hydrazine engine, not KeraLOX. There is NO way that RD-180 is similar to Agena.

Delta IV won't be man-rated anytime soon...

NASA has many standards in the post SS activity. Deltas, with their continuous refueling requirement, just won't get there. The new standard is KeraLOX-friendly. Expect CST-100 to go up on RD-180 with a backup plan for Falcon 9. I agree with earlier posts that advise that all of these launchers use a standardized control approach, so that CST-100 and Dragon 2 would be adaptable to any other approved rocket-system.

ULA cannot change their rockets. Boeing and Lockheed would have to do this on their own. CST-100 is a Boeing (not ULA) system.

NASA boffin: RIDDLE of odd BULGE FOUND on MOON is SOLVED

Beachrider

Re: Of course, had we not abandoned the Apollo project...

The problem with settlements on Luna is that no one has built 'self sustaining settlements' models. Several have tried, but the 14-day 'sun is up' followed by the 14-day 'sun is down' diurnal-cycle has been problematic. It creates very large temperature swings.

The interesting discussion about polar settlements (where this 28-day cycle MIGHT be less severe) haven't borne fruit, either.

There is quite a lively discussion about water+mineral availability, but 99%+ of Luna is drier than Atacama.

This rocket is NOT about ISS...

This is a deepspace rocket system that can fly to a Lagrange point and fly back. With improvements, it might even go to Mars or a deepspace station. The Russians don't do any of THAT.

At any rate, SpaceX expects to gain more ISS/LEO work that reduces the Russians in 2018. They are going after Arianespace in the open-commercial launch business before that, too.

Snowden leaks latest: NSA, FBI g-men spied on Muslim-American chiefs

Beachrider

This is not EASY stuff...

Governments are correctly taken-to-task for abuse of people, even when they are attempting to protect some people from other people. The Japanese Internment of 100,000 people in four US states during WWII is one example. Kipling's "White Man's Burden" was a rallying cry at the dawn of the 20th century, is horribly condescending now.

The criticism for the actions is just. A lot of important, valuable gains have been made from actions that would be horrible to do today.

Software giant CA Technologies dumps arcserve biz

Beachrider

Re: Another product ruined by CA

I don't think that Arcserve surged its marketshare after purchase. It was retracked as a security-oriented suite of data protection products. The visionaries from Cheyenne departed a year before the CA acquisition. As I recall, the network bandwidth was a severe constriction for Arcserve with the then-largest setups. CA was investigating hardware solutions (Fibrechannel, etc.) to help make the backup/recovery aspect more viable.

Arcserve in the mid-1990s...

I worked for CA when they acquired Arcserve. At the time, they had the best 'Enterprise Backup' operational software, especially if you had NetWare fileshares. We had a fat-laptop with a SCSI tape that we used to demonstrate function at user sites. That is NOT to say that it worked perfectly.

I still am not pleased with the bullet-proof measures in common Enterprise Backup systems. We rarely get 100% correct backup on any given night. We have tried 5 vendors in 12 years. I think that most datacenters underallocate staff to maintain the various mechanisms of Enterprise Backup.

Oracle shares pummeled after giant reports glacial growth

Beachrider

Oracle is sometimes inflexible on privacy...

In the USA, there are 'HIPAA' privacy rules, particularly surrounding healthcare information. The big prosecutors in the USA have been quite active prosecuting violations of 'protected health information'.

Caregivers don't want to pay for violations done by their business-partners, so they get agreements from partners to pay the fines IF the partner is the cause.

In my state, Caregivers are sharing that Oracle is not signing such agreements. This is making it easier to choose vendors (or transition to vendors) that sign these agreements.

It is not good for Oracle growth in the Caregiver sector of the economy.

US MARTIAN FLYING SAUCER tests above Hawaii: postponed

Beachrider

Martian landings...

NASA is trying to get a more-general capability for Mars landings, particularly with heavier payloads and higher martian-altitude landing sites.

Using rockets all the way down would require a substantial fuel supply for those long burns, there is enough atmosphere on Mars to cause the burns to start early and run for a long time.

Using parachutes all the way down leaves a lot of energy to be dissipated by short-burn rockets or rockets+bags. This is acute for higher-altitude landings and/or massive probe landings.

Both Viking and MSL were just under 1 ton. With larger loads, this kind of hybrid air-friction tool saves precious weight on fuel and large landing rockets. It will be cool on probes anticipated for 2020 and beyond.

There were 14 Venera probes. None of them moved. Of the six landers before 1978, none of them lasted much more than an hour. The last 4 landers lasted between 1 and 2 hours. Not bad for 1970s technology. They really aren't to be compared to MSL, though.

US space-station crisis: 'We have enough of our own problems' sighs Russian deputy PM

Beachrider

Re: The Russians are NOT saying that they will cease flights BEFORE 2020...

NASA agreed with me today. Russia cannot close the ISS. They can stop participating if they want. The USA can use its commercial lift (Dragon & CST100) if they are ready by 2020. Russia has signed to provide services through 2017 and support through 2019, currently.

The Russians are NOT saying that they will cease flights BEFORE 2020...

Simply put, the USA might not need Russian flight support after 2018. Another thing, the Russians cannot prohibit access to the ISS, they can only withdraw from the Memorandum of Understanding about SUPPORTING the ISS. Read the 1998 MOU on the ISS between RSA and NASA

Space Station in CRISIS: Furious Russia threatens to BAN US from ISS

Beachrider

The Russians can withdraw, but not close the ISS

Roscosmos is committed to support the ISS through 2020. According to the 1998 NASA-RSA agreement (MOU), the RSA can withdraw anytime they want after that.

At current plan, the NASA commercial manned-LEO-lift ability will come online in 2017. A second commercial vendor to come online by 2018.

Orbital-Antares (5) & ULV-Atlas (2+) claim to warehouse enough Russian-sourced equipment to last years. SpaceX-Falcon and ULV-Delta use NO Russian-sourced equipment. Both Dragon and CST100 attach to their rockets with the same technology and controls, so CST100 could launch with Dragon rockets (whenever THAT gets tested).

ESA Ariane 5/6 would certainly be considerations, as would JSA H-IIA/B.

Boeing's SLS isn't planned for use with the ISS. It comes online by 2020, but is priced for more distant targets.

In short, permanent separation of Roscosmos from ISS is a horrible shame. It might bring about the closure of ISS after 2020. There are other Space Station plans that could take advantage of the opportunity by that time, though.

SpaceX wins court injunction to block US Air Force buying Russian rockets

Beachrider

It is easy to find conspiriacies, with the right outlook...

There ARE real issues with SpaceX going down a different road than others. Musk is NOT getting security clearances the same way that Lockheed and Boeing do. This lets him hire faster, but gets in the way of corporate-clearances issues.

I am a US taxpayer. I want the costs lowered. Since Atlas uses Russian-made rockets, they can continue with their current inventory and transition to US manufacturing IF they get $1Bn to build that manufacturing. Elon wants that 1 BN in his pocket, instead.
