Astra, a space start-up company based in California, emerged as the latest rocket builder to reach space.
On December 15, in their second attempt, they successfully launched Rocket 3.2 vehicle from Kodiak, Alaska after the failure of Rocket 3.1 on September 11 due to a problem in the guidance system. The test flight, with the objective of arriving in orbit, reached up to a maximum altitude of 390 kilometres with a maximum speed of 7.2 kilometres per second, but failed to attain necessary velocity to achieve the orbit as the launcher ran out of fuel. Astra officials stated that the 11.6 meters tall Rocket 3.2 performed magnificently for approximately 8 minutes. The flight demonstrated the launcher’s first stage with Five kerosene-fuelled Delphin engines burning for 2 minutes and 22 seconds, payload fairing separation three seconds later followed by separation of the first stage and successful ignition of the second stage engine. After shutting off its upper stage, the test flight simulated activity to deploy payload into space although there were no onboard satellites. With the significant success from the present launch, Astra is planning to add a payload into their next flight Rocket 3.3 that is scheduled for early 2021. The company intends to come up with upgraded versions like Rocket 3.3, 3.4 and many more to increase performance and deliver a payload into orbit at a reduced cost that has never been possible before. This success from the private start-up company is the route for many start-ups to enter the competition in the space domain

A grounded look into the skies: The Ground Station Project

(…) How can we predict the weather? A key part of this, and several other technologies, are ground stations! Surely it can’t be easy to design, manufacture and implement one of these, right? Well, whilst it is indeed not trivial, it is also not something that’s out of our reach! Here at PoliSpace, members of the SpaceTech group have been working on what has been labeled The Ground Station Project.

Spark of Innovation: A Brief History of Electric Propulsion

When we think of rocketry, we commonly think of the impressive images and videos of spacecrafts being launched utilizing huge earth-shaking rockets, propelled through the skies by a scorching trail of exhaust and flames. These are our traditional thermochemical rocket thrusters, and since the advent of rocketry, they have been our most reliable way to get things out of our planet.
