As
use of the International Space Station (ISS) increases, demand for
cargo resupply, cargo recovery, and reboost services is expected
to increase. The K-1 vehicle represents a viable solution for such
missions.
For an ISS resupply mission, RPK would switch out the K-1's
payload module for an ISS Cargo Module. The ISS
Cargo Module can carry experiment racks, equipment, and supplies
to the ISS. In addition, pre-packaged cargo modules (such as medical
units or laboratories) can stand ready at RPK's launch site
for quick response in case of emergency.
With the ISS Cargo Module, RPK can provide safe and efficient
rendezvous and berthing with the ISS and meet the ISS Visiting Vehicle
requirements.
The K-1 will be able to deliver up to 6,118 lbm (2,775 kg) of pressurized
cargo to the ISS and return up to 6,118 lbm (2,775 kg) of recoverable
downmass. The K-1 is also capable of providing up to 25 miles (40km)
reboost and attitude control for the ISS, an important feature for
maintaining the ISS orbit.
Use of the K-1 for select ISS missions would represent significant
cost savings for NASA and its partners, who must balance diminishing
budgets with increasing demands. At the same time, routine K-1 missions
to the ISS would expand research opportunities and scientific utilization.

The K-1 grapples with the arm, then berths to the ISS to transfer cargo.
The K-1 can recover cargo from the ISS, returning 6,118 lbm (2,775 kg)
of equipment, supplies, and experiments on each mission.
