The LDPE (Long Duration Propulsive ESPA) is based on a Northrop Grumman payload adapter used to help attach the upper stage to the main satellite in addition to hosting a few slots for other smallsats. However, the entire system is powered by the ESPAStar satellite bus, which is in charge of power consumption and distribution as well as ...

NASA's Long Duration Exposure Facility, or LDEF (pronounced "eldef"), was a cylindrical facility designed to provide long-term experimental data on the outer space environment and its effects on space systems, materials, operations and selected spores' survival. [2] [3] It was placed in low Earth orbit by Space Shuttle Challenger in April 1984.
Alongside STPSat-6 was an integrated propulsive EELV Secondary Payload Adapter (IP-ESPA) holding up to six payloads. [32] The STP-3 mission also debuted three engineering features designed to reduce risk and accumulate flight experience before use on Vulcan Centaur : an Out-of-Autoclave (OoA) payload fairings, an in-flight power system and GPS ...
Following a three-year hiatus, SpaceX’s Falcon Heavy rocket celebrated its second successful launch in two months, lifting off Pad 39A at NASA’s Kennedy Space Center in Florida at 5:56 p.m. ET ...
Electron is a two-stage, partially reusable orbital launch vehicle developed by Rocket Lab, an American aerospace company with a wholly owned New Zealand subsidiary. [14] [15] Servicing the commercial small satellite launch market, [16] it is the third most launched small-lift launch vehicle in history.
Liftoff is now on track for no earlier than 5 p.m. ET (4 p.m. local time) Thursday from SpaceX’s launchpad at its Starbase facility near Brownsville, Texas. The window for launch will remain ...
For rockets and space vehicles, propellants usually take up 2/3 or more of their total mass. Large upper-stage rocket engines generally use a cryogenic fuel like liquid hydrogen and liquid oxygen (LOX) as an oxidizer because of the large specific impulse possible, but must carefully consider a problem called "boil off," or the evaporation of the cryogenic propellant.
