------- UPDATES -------
• Starship static fire today. 600HzONK was heard. Debris flew again. Mysterious drip seen falling down... might not be a problem? Elon might give us elevenses with a second static fire
• Dress rehearsal for Crew-1; expected launch 15th November (45thSpaceWing gives 70% chance of favorable weather conditions)
• Jim warns of gap after retirement of ISS but who gives a shit it’s more expensive than a high school girlfriend
• Chinese “private” company Galactic Energy launches new four-stage rocket (Nov 8)
• India launches 10 satellites into polar orbit aboard; first launch since start of pandemic (Nov 7)

------- THIS DAY IN SPACEFLIGHT -------
• Death of American astronomer Percival Lowell, who helped fuel the infamous “Martian Canal” theory and set up the Lowell Observatory leading to the discovery of Pluto (1916) (b. 1855)
• Voyager I makes closest approach with Saturn; captures first ever close-up view of the ring system (1980)
• STS-2 lifts off using the Columbia orbiter, marking the first time a manned craft is launched into space twice
• Death of Russian engineer-cosmonaut Aleksandr Serebrov (2013) (b.1944)
• The ESA’s Philae lander is deployed from the Rosetta probe and reaches the surface of Comet 67P (2014)

--UPDATES--
• Raptor SN36 installed on SN8
• Concrete and Nitrogen delivered to Boca Chica
• Ariane 6 delayed (yes we all expected it)
• Rhetoric over Results
• SLS delayed (no this is not a joke, it was supposed to do its test this week)
• China will probably launch a rocket in the next week without telling anyone
• Blue Origin fixed a problem with their turbopumps; more importantly they fixed the clogged pump to the break room coffee machine
• Canada probably did something with their little arm?

Next scheduled launch: Rocket Lab's Electron Rocket on October 28th
A Rocket Lab Electron rocket will launch on its 15th flight with the CE-SAT-2B Earth-imaging microsatellite for Canon Electronics and nine SuperDove Earth-imaging nanosatellites for Planet. Rocket Lab nicknamed the launch “In Focus” in reference to the Earth observation payloads on the mission. Delayed from Oct. 20 due to poor weather forecast. Scrubbed on Oct. 21 to assess sensor data.

>Under 24 hours til launch of Falcon 9 w/ NROL-76 payload.
>"A SpaceX Falcon 9 rocket will launch a classified spacecraft payload for the U.S. National Reconnaissance Office. This will be SpaceX’s first launch for the NRO. Delayed from April 16."
>https://spaceflightnow.com/launch-schedule/

Also, looks like the launch schedule of SLS is sadly starting to slip again

>It's looking likely that the first flight of NASA's new heavy lift rocket, the Space Launch System, will slip beyond its November 2018 launch date

Hey guys I'm trying to figure out the flight of a rocket in terms of velocity and height at any given time. I started with F=ma and changed it a = F/m, then I changed F to thrust (T) and m to (initial mass of rocket - (flow rate)(time))

which lent me the equation for acceleration

a(t) = T/(Mo - Flow(time)) - g

where T=thrust, Mo= initial mass, and g is the acceleration due to gravity

First of all, I'm wondering if I've done this bit right, second of all, I don't really know how to integrate this to achieve the velocity formula and how to go from there to the equation for height

I've looked at a few different equations for the velocity of a rocket at a given time but I'm having difficulties with the variables they use, and I still don't know how to get to position

Thanks for any help you guys can offer, and space general maybe?

>NASA has now scheduled the telescope for a 2018 launch, though outside analysts suggest the flight could slip past 2020.

>In May 2007, a full-scale model of the telescope was assembled for display at the Smithsonian's National Air and Space Museum on the National Mall, Washington DC. The model was intended to give the viewing public a better understanding of the size, scale and complexity of the satellite, as well as pique the interest of viewers in science and astronomy in general.

Will this get cancelled?
