When Elon Musk crawled over the performance of the SpaceX Raptor engine and the Cygnus of Northrop Grumman from the International Space Station (ISS), rubble observers ruined the 10th anniversary of the first random Hypervelocity satellite collision.
February 10, 2009 A 950kg Russian military satellite crashed into an Iridium Comms bird, destroying both starships and leaving behind a cloud of debris that frightened Sandra Bullock.
The Russian satellite, originally launched in 1993, was out of service and had no propulsion system. Iridium 33, however, went well until that day. The two were expected to pass each other up to 584 m, but eventually collided. This demonstrated the need to better track data and create a cloud of more than 2,000 pieces of debris, some of which required the ISS to perform an unusual evasive maneuver
Since then, the debris has begun to reenter the Earth's atmosphere, but the incident remains a salutary reminder that the orbital space is a little crowded. It is also a justification for provisions requiring that satellites may either be sent into cemetery orbit at the end of their mission, or have sufficient maneuverability to cause themselves a fiery death in the direction of Terra Firma.
Nobody needs a real life continuation of the vehicle Clooney and Bullock Gravity .

Also returned to Earth is the freighter of Cygnus by Northrop Grumman after 81 Days connected to the ISS.
The spaceship – numbered NG-10 and named "SS John Young" in honor of the lunar converter that died last year – was loaded with more than 2.5 tons of garbage from the space station for disposal as the thing eventually burned in the atmosphere ,
Unlike SpaceX's Dragon, the Cygnus does not have a soft landing and certainly not in one piece.
However, the Cygnus was put into service after its 8 February departure from the ISS. The spaceship will be in orbit for a little longer, deploying nano satellites and testing a communication system before it is killed.
Already 62 miles above the ISS orbit, there are two Cubesats launched from a SlingShot mechanism on the ISS through SpaceX's CRS-16 mission and installed by the Orbital Outpost crew in the Cygnus.
The hard-working spacecraft is also expected to provide two more satellites for NanoRacks in the form of the United on February 13. MySat-1 of the United Arab Emirates and CHEFSat of the US Naval Research Laboratory (CHEFSat) of the US Naval Research Laboratory is not an indication that Gordon Ramsay should be shot into orbit, but the low-cost high-frequency satellite.
The final task for Cygnus will be KickSat-2, a CubeSat, which in turn will deploy 100 tiny ChipSats that integrate 2 power, computing and sensing devices on a 3.5 cm board ,
The Cygnus will finally be available from February 25th.
Musk Feels Pressure
Back on Earth, Elon Musk praised the virtues of the SpaceX Raptor engine and proclaimed that the power plant has now reached a chamber pressure of 268.9 bar, a higher pressure than the venerable Russian RD 180 engine used to power the Atlas V of United Launch Alliance.

While ULA is trying to replace Jeff Bezos and his Blue Origin rocket players to replace the RD-180 SpaceX's use of Raptor remains problematic for the next generation of Musk rockets. ®
