Posle više od godine priprema i odlaganja australijska firma Gilmor Spejs noćas po našem vremenu lansira raketu Eris 1. To je trostepena prečnika dva metra i visine 25 metara. Treba da omogući lansiranje satelita mase do 215 kg u heliosinhronu orbitu na visini od 500 km.
Heliosinhrona orbita je polarna orbita kod koje satelit uvek preleće istu tačku na Zemljinoj površini u isto lokalno vreme.
Interesantno je da je pogon Erisa 1 hibridni, tj. gorivo je u čvrstoj formi, sa kanalima u gorivnom bloku kroz koje dotiče oksidans i u kojima dolazi do sagorevanja na površini njihovog dodira. Ovaj koncept bremenit je problemima, pa jedva da je neko pokušao da napravi takvu raketu.
Ovo neće biti prvi put da se kosmičke rakete lansiraju iz Australije. Naravno, to su radili britanci, zadnji put 1971. Njihova Crna Strela bila je vrlo interesantna, ali bankrotirano kraljevstvo nije moglo da priušti više od nekoliko lansiranja.

Otkazali lansiranje. Razlog: nekontrolisano se otvorio teretni prostor.

Citat:Both the U.S. Department of Defense and NASA quietly moved this week to urge competitors to Elon Musk’s SpaceX to expedite their development of alternative rockets and spacecraft after a spat on social media earlier in the week between U.S. President Trump and Elon Musk.
According to reports from the Washington Post, officials were extremely concerned by the conflict between Trump and Musk, during which the President threatened to pull government contracts from companies owned and operated by Musk, like SpaceX and Tesla, leading Musk to announce, but later recant, that SpaceX would begin to immediately decommission its “Dragon” spacecraft, stunning officials at NASA, potentially leaving them with no way to transport astronauts or cargo to the International Space Station (ISS).
One NASA official said that watching the feud between Trump and Musk play out on social media Thursday at first was “entertaining.” But once Musk called for decommissioning Dragon, “it turned really terrifying,” with a similar reaction happening at the Pentagon.
Since Thursday’s exchange, at least four commercial space companies, Sierra Space, Rocket Lab, Stoke Space and Jeff Bezos’s Blue Origin, have been contacted by government officials about the status of their rockets and when they might be available for government missions, due to ongoing concerns about SpaceX and their reliability under Elon Musk.
