The Falcon Heavy will be an impressive launcher if it can ('scuse the pun) get off the ground. A bit of mis-advertising in that saying its the most powerful launcher since the Saturn V. STS can put close to Saturn V levels of weight into LEO, the only difference being that every STS launch has the dead weight of the Orbiter, which puts the payload mass down to 22,000 kilos.

Still though, its great to see something happening in the space industry, I could see Elon going for the Human altitude record with a Lunar flyby. Its currently held by the crew of Apollo 13 Smile

I'm pretty sure the Soviet Union holds the record for the Tortoise altitude record Razz

Looks like NASA will be unveiling the all new Shuttle Derived Heavy Lift Vehicle (SDHLV) and announcing contracts in the summer. The SDHLV will dwarf the Falcon Heavy, and stand very tall in the Space Coast sky, its initial 70mT payload will be evolved to an eventual 130mT, which would be bigger and more powerful than the Saturn V. At the moment it looks like will be using two 5-segment Solid Rocket Boosters, three SSME's, a stretched Shuttle ET with a stage adapter on top and two J-2X engines for the upper stage. It uses hardware from both the Apollo (J-2 derivative, J-2X) and STS.

Expect to see mission architectures and a timetable for milestones for the SDHLV and MPCV (Orion Crew Capsule) programmes.

Wether or not there will be funding for these remains uncertain, but NASA still runs on a budget much much much larger than PKA or ESA, so hopefully they can build something before 2020.. If all goes to plan, hopefully we will be seeing trips to the Earth-Moon L Points (areas where you can stand still relative to the Earth and the Moon), trips to Asteroids and trips back into Lunar Orbit... hopefully...

Yep Nicky they say it's supposed to be as tall as the Saturn V and wider, in terms of "aww" factor for the machine... we'll have to wait and see. I highly doubt it'll be as amazing as a Saturn V which is still the 2nd loudest man made noise... only 2nd to the atomic bomb

There is a seperate team at MSFC looking at a Saturn V type all-liquid vehicle, even with rumours of using surplus F-1 engines from the S-1C stage of the Staurn V..

Lots of detail here

Post by Radiation Louis on Mon 11 Apr 2011 - 17:24

great find nicky, but something about it doesn't add up, Any extra Saturn V engines are all in museums and another 10 are attached to 2 Saturn V's which are on display at NASA's Cape Canaveral FL and Birmingham AL so using surplus doesn't make sense and if there are surplus those engines would need some serious restoring. What I think if they are going to do something like this is get their hands on a F-1 engine and take it appart, and make all new F-1's from that because i highly doubt they would take engines that are in museums and use them, because to the best of my knowledge those are the only surplus there is and they are all over the world.

True that. Perhaps thats what the article meant, to take the F-1's apart and manufacture a new batch while they try to find an alternative.

Smaller engines like the Russian RD-180 in clusters might do the trick too, but the Soviet N-1 rocket is a great example of why not to use big clusters of smaller engines... America needs big engines for such a big launcher!

just as I thought, while yes your right nicky that they are F-1 engines but also like i had said, they have just been modernized the RP-1 engine is the F-1 engine just it can run on different types of Fuel, noteably kerosene, which can be stored at room temperature and would mean they would not have to use insulating Foam on the fuel tank that has cause concern for shuttles and 1 tragedy

STS-134 mission outlined here, one of the interesting parts of it is that they will undock from station, fly a large distance away, and then rendezvous with station again to test out Orion navigation systems for NASA's next spacecraft, complete with Apollo style techniques for rendezvous and approach Smile

Hey, it was 50 years ago today that Vostok 1 was launched from the Kazakh SSR!

And its 30 years to the day that John Young and Bob Crippen flew on the STS-1 mission of Columbia! Its the Space Shuttle Programme's 30th Birthday!

Just downloaded a great book for free today! (Yuri's Night you see). Its called Martian Summer, and it basically chronicles Andrew Kessler's 90 days working on the Mars Phoenix Lander team as some who is recording the story of the mission, rather than being a scientist. He describes it as ''winning the nerd lottery''. Its quite a quirky little read, and well worth the 0 pence price if you like reading about things like this.

Just came across this before posting... made me chucle a bit. Gives you an idea of the kind of humour this guy has.
Bob Bonitz from the robot arm team drops his load
in Bill Boynton’s TA. That’s science jargon for the RA putting dirt
into TEGA’s thermal analyzer (TA).

Another important space anniversary coming up.

April 14th, 41 years after flight day four of the Apollo 13 mission. MCC Houston gives the command to the crew to stir the H and 02 tanks. Damaged teflon allowed the wires leading to the stirring fans to short circuit, igniting the insulation and blowing up the tank.

''Houston, we've had a problem''

Shuttle ''Successors'' contracts are named today. Four different spacecraft, all capable of flying to low earth orbit, like the shuttle, but lack the massive cargo capability of the shuttle. These four craft are:

CCST - Boeing - $92m
Dream Chaser - SNC - $80m
Dragon - SpaceX - $72m
New Shepard - Blue Origin - $22m

The CCST is an Apollo shaped craft, but bigger! Although not as big as the Orion Crew Module that NASA are building. CCST would ferry Astros to the ISS and to the private Bigelow Inflatable Space Station (i'm not kidding on about that last detail). It lands on land under good ol' chutes.

Dream Chaser - Mini-baby-Shuttle! Small winged lifting-body orbital spaceplane. Its tiny compared to a Shuttle, and will look quite odd launching atop an Atlas rocket, unshrouded. Its very similar to Soviet proposals for orbital military space planes. It can land on conventional runways too. Which is handy.

Dragon - Its already flown without men in it in an orbital test flight lasting around three hours. The crewed version will have a launch abort system and landing rockets, so it can LAND when it comes home, rather than splashing down or striking the ground really hard.

New Shepard - I know nothing about this.

STS-134

Who's up for another shuttle launch? 134 is going up on Friday. A much better celebration than the royal wedding. Its the last mission of Endeavour, the ship built to replace Challenger, and the penultimate mission of the Space Shuttle Programme. This mission was originally scheduled to be the final flight of the SSP, but STS-135 has been added to the manifest.

STS-134 will deliver the Alpha Magnetic Spectrometer 2, an instrument that will allow astronomers to observe the universe in new ways, searching for unusual matter by measuring cosmic rays. It will also bring up the ELC-3 Cargo pallete which will carry spare parts for the station.

Endeavour will be doing some rather unusual things on her final mission. She will be the first to undock from station and re-rendezvous again in order to test out navigation systems for a future NASA spacecraft that will replace the Shuttle. She will also leave behind the Orbiter Boom Sensor System, used for looking for damage to her thermal protection system, which will be used on the ISS to aid with repairs to solar panels.

This will be the final mission to carry six Astronauts, as STS-135 will carry just four Astronauts. STS-134 will also be the last Shuttle mission to carry a foreign traveller, in this case a European Spationaute. The entire crew is made up of veteran fliers.

CDR - Mark E. Kelly - USN/NASA - 4th Spaceflight
PLT - Gregory H. Johnson - USAF/NASA - 2nd Spaceflight
MS1/EV2 - Michael Fincke - USAF/NASA - 3rd Spaceflight (first Shuttle flight)
MS2/FE - Roberto Vittori - IAF/ESA - 3rd Spaceflight (first Shuttle flight)
MS3/EV1 - Andrew J. Feustel - NASA - 2nd Spaceflight
MS4/EV3 - Gregory Chamitoff - NASA - 2nd Spaceflight

CDR - Commander, PLT - Pilot, MS - Mission Specialist, FE - Flight Engineer, EV - Spacewalker

Launch on Friday! Check here for streams!

A pic of the first successor to the Shuttle being built! The Orion MPCV has had its thermal protection system added, and will be used as a Test Article. Its basically the MPCV equivalent to Space Shuttle Enterprise.

Perhaps one day one of these will be carrying humans to the Martian system for the first time? Or perhaps to an Asteroid, where only Bruce Willis has gone before?
