NASA and the White House have officially released their FY2013 budget proposal, the first step of the Congressional budget process. As mentioned previously on Slashdot, the proposal decreases Mars science funding (including robotic Mars missions) down to $361M, arguably due in part to cost overruns by the Webb telescope. The proposal also lowers funding for the in-house SLS rocket and Orion capsule to $2.8B, while doubling funding for the ongoing competitive development of commercial crew rockets/vehicles to $830M. Ranking member of the Senate science committee, Sen. Hutchison (R-TX), expressed her frustration with 'cutting SLS and Orion to pay for commercial crew,' as it would allegedly make it impossible for SLS to act as a backup for the commercial vehicles.

At a talk at the National Press Club, SpaceX's Elon Musk revealed the company's plans for making their Falcon 9 rocket fully reusable. A rendering depicts the first stage, upper stage, and Dragon capsule all separately returning to the Earth's surface and making a controlled rocket-powered landing. During the next few years SpaceX will be testing VTVL maneuvers and reusability with their Falcon 9-based 'Grasshopper' testbed, with up to 70 test launches per year. Musk stated that if reuse is successful it would result in a 100x reduction in their already-low launch costs, a key step towards Musk's long-term aim of lowering the price of a ticket to Mars to $500K.

Besides using the SpaceX Dragon capsule to deliver supplies to the ISS this year and astronauts in following years, the company wants to use Dragon as a platform for propulsively landing science payloads on Mars and other planets. Combined with their upcoming Falcon Heavy rocket, 'a single Dragon mission could land with more payload than has been delivered to Mars cumulatively in history.' According to CEO Elon Musk, SpaceX is working with NASA's Ames Research Center on a mission design concept that could launch in as early as 5-6 years.

Utah congressmen Orrin Hatch, Bob Bennett, Rob Bishop, and Jim Matheson issued a statement claiming that NASA's design process for a new congressionally-mandated heavy-lift rocket system may be trying to circumvent the law. According to the congressmen and their advisors from solid rocket producer ATK, the heavy-lift legislation's requirements can only be met by rockets utilizing ATK's solid rocket boosters. They are alarmed that NASA is also considering other approaches, such as all-liquid designs based on the rockets operated by the United Launch Alliance and SpaceX. ATK's solid rockets were arguably responsible for many of the safety and cost problems which plagued NASA's canceled Ares rocket system.

The BBC reports that the space agencies of Europe, Russia, and the US are in (very) preliminary discussions about a potential collaborative mission where astronauts would assemble a small spacecraft at the ISS, then fly it around the Moon and back. This is somewhat similar to previously-proposed commercial missions, with many elements adapted from spacecraft systems already in existence. This would also be a testbed for eventual asteroid and Mars missions, which would likely require modules to be launched on multiple rockets and assembled in space.

NASA is spending a total of $475,000, split between Masten Space Systems and John Carmack's Armadillo Aerospace, for a series of seven test flights of the companies' reusable suborbital rockets over the next several months, going to altitudes as high as 25 miles. NASA's goal is to foster a more cost-effective and flexible way to conduct microgravity and upper-atmosphere research. Jeff Bezos's suborbital spaceflight company Blue Origin has also been making steady progress this year on their $3.7M contract to test pusher-escape system and composite pressure vessel technologies, which NASA is interested in for orbital spaceflight.

At the recent Joint Propulsion Conference, SpaceX's rocket development facility director Tom Markusic unveiled conceptual plans for how its current Falcon 1 and Falcon 9 commercial rockets can be evolved into heavy-lift rockets, ranging from a Falcon X capable of lifting 38,000kg to orbit, up to a 140,000kg Falcon XX (more than either the Saturn V or the 75,000kg shuttle-derived rocket Congress currently plans on having NASA spend >$13B building). SpaceX presentations also discuss a new Merlin 2 heavy-lift engine, solar-electric cargo tugs, adapting their current engines for descent/ascent vehicles fueled by Mars-derived methane, and a desire for the government to take the lead on in-space nuclear thermal propulsion while commercial focuses on launchers. In a recent interview, SpaceX CEO/CTO Elon Musk expressed his goal of lowering the price of Mars transportation enough to enable early colonization in 20 years, and his own plans for retiring to Mars.

Six weeks after the first launch of SpaceX's Falcon 9 rocket, the first stage of the second rocket has finishing production/testing, and has arrived at Cape Canaveral for a launch as early as September, depending on the pace of a methodical review of the Dragon capsule systems and minor rocket modifications/fixes being made based on data from the inaugural launch. The rocket will launch the first operational unmanned Dragon cargo/crew spacecraft into orbit, where it will perform tests and then reenter off the California coast. CEO/CTO Elon Musk made the intriguing remark that Dragon's heat shield is strong enough to enable a return not only from Earth orbit, but also lunar orbit or Mars velocities as well.

The German Aerospace Center is planning to launch a novel reusable spacecraft in 2011, incorporating flat damage-resistant tiles. Nitrogen will be pumped through the porous tiles, creating a protective gas layer that actively cools and shields the hottest parts of the spacecraft from the searing heat of reentry. The 12.5M-euro unmanned 'SHEFEX II' project is a major technological step towards the team's eventual goal of a reusable space glider which will be cheaper and easier-to-build than NASA's space shuttle.

Members of the Senate Committee on Commerce, Science, and Transportation are drafting a bill (due this week) which slashes NASA technology development/demonstrations, commercial space transportation, and new robotic missions to a small fraction of what the White House proposed earlier this year. The bill would instead redirect NASA funds to 'immediate' development of a government-designed heavy lift rocket, although it's still unclear if NASA can afford a heavy lifter in the long term or if (with the new technology the Senators seek to cut like in-space refueling) it actually needs such a rocket. The Senators' rocket design dictates a payload of 75mT to orbit, uses the existing Ares contracts and Shuttle infrastructure as much as possible, and forces use of the solid rocket motors produced by Utah arms manufacturer ATK.

Following up on a story a few days ago about an unmanned Russian cargo ship's initial aborted attempt at docking with the International Space Station, the vehicle made a second pass on July 4 which succeeded. Russian engineers believe the initial abort was triggered when the (normally reliable) Progress spacecraft detected interference between a remote control system on the ISS and the Progress's camera, and successfully docked on the 2nd try by using the autonomous system instead.

Boeing has released a number of new details on the development of their CST-100 manned space capsule being developed in collaboration with commercial space station builder Bigelow Aerospace. Competing with SpaceX's Dragon capsule, the vehicle is designed to be compatible with existing Atlas V, Delta IV, and Falcon 9 rockets, and is planned to carry 7 people in a capsule 'a little smaller than Orion, but a little bigger than Apollo.' Funding was jump-started this year with $18M of fixed-price Commercial Crew Development funding from NASA, which requires completion of several fabrication and demonstration milestones this year (heat shield, escape system, landing tests, etc.) in order to get the full payment.

Following up on the successful first launch of their Falcon 9 rocket, SpaceX has signed a $492M deal for launching several dozen satellites for the Iridium NEXT constellation, the biggest commercial launch deal ever (teleconference notes). This is a needed boost for the US launch industry, which has dwindled to a fraction of the international market due to problematic ITAR arms regulations and high costs. SpaceX's next launch is scheduled for later this summer, carrying the first full version of the Dragon reusable capsule, which will run tests in orbit and then splashdown off the California coast.

In a surprise move in the battle between NASA and certain members of Congress over NASA's future direction, NASA has told its contractors to cutback nearly $1 billion on this year's Ares/Constellation program, stating that the cutback is necessary to remain in compliance with federal spending laws requiring contractors to withhold contract termination costs. While complying with budgeting laws (and in line with NASA's desire to cancel Constellation), this move is also potentially in violation of a 2010 appropriations amendment by Sen. Shelby (R-AL) and Sen. Bennett (R-UT) which prohibits NASA from terminating any Constellation contracts. If NASA's move goes through, the biggest liability is $500M for ATK, the contractor who is/was responsible for the first stage of the Ares I medium-lift rocket.
