Ipsa One is an association (đParis) that gather about 60 students passionned by SPACE.
Our project? Building a propelled 3U CubeSat. Ready to join the mission?
@IanJohnBuckley@ea4gpz 6740 km from the center of the Earth. So the software (GMAT created by @NASA) counts the radius of the Earth in this value. The apogee of the orbit is only 369 km. So area and drag are indeed a factor that can not be neglected, especially when our mission is to counter drag.
See how the semi major axis (longest diameter of an ellipse) decreases through time. The decline ramps up as the mass of the orbiting satellite increases. đ§đ°ïž

First take a high-resolution digital model of the #Moon, accurate down to 5 m, then combine it with historic #lunar instrument data, to gain highly-accurate and scientifically valuable recreations of missions such as @NASA's #Apollo15 and @ESA's #SMART1 https://t.co/8OHSsdvnvI
Japanese satellite company Synspective signed a deal with Rocket Lab to launch the StriX-α synthetic aperture radar satellite on an Electron rocket later this year from New Zealand.
It will be the first in Synspectiveâs planned StriX constellation of around 25 SAR satellites.
