The Defense Advanced Research Projects Agency (DARPA) is requesting $175.24 million for fiscal year (FY) 2017 for the development of space systems and technology, an increase of $48.5 million over current fiscal year spending.

The ambitious XS-1 program, which aims to develop fully-reusable launch vehicle system, once again tops DARPA’s space spending with proposed spending of $50.5 million. The program received $30 million for FY 2016.

DARPA has been funding three teams to develop XS-1 launchers: Boeing and Blue Origin, Masten Space Systems and XCOR Aerospace, and Northrup Grumman and Virgin Galactic.

The defense agency plans to down select to one contractor that would produce a launch vehicle. Officials have not said when that decision would be made.

A critical design review on the vehicle to be built and tested is scheduled for FY 2017. The contractor would also being to fabricate flight and ground system hardware during that upcoming fiscal year.

While XS-1 would continue, DARPA is ending the Airborne Launch Assist Space Access (ALASA) launcher program after budgeting $80 million for it over two fiscal years.

ALASA aimed at developing a rocket that could place a 100 lb (45 kg) payload into low Earth orbit for less than $1 million per launch using an unmodified F-15 fighter. Tests indicated that Boeing’s mono-propellant had a tendency to explode. DARPA is now evaluating alternative launch systems and propellants.

The research agency has requested significant increases for three on-going programs named Radar Net, Hallmark and Robotic Servicing of GEO Satellites. Spending on the programs would increase by a combined $54 million.

The Space Surveillance Telescope would see a modest budget boost from $9 million to $10 million. Project Phoenix, which is developing technologies for in-space satellite servicing, would see its budget decline from $19 million to $8.74 million.

DARPA is also planning to end two other programs: Space Domain Awareness and Optical Aperture Self-Assembly in Space (OASIS).
