Today is also Boston University's Giving Day! Support our team by donating with the link below (donate to Rocket Propulsion Group). Help us achieve more incredible milestones like our first liquid rocket launch. Thank you all for the support!

On March 29th, BURPG successfully launched and recovered Icarus. Preliminary analysis shows it flew to approximately 13,000 feet. This is the first liquid bipropellant rocket BURPG has launched in its 22 year history. Massive congratulations to the team for a spectacular launch!

Last Saturday, BURPG successfully completed a fully integrated vehicle hotfire of our new bipropellant liquid rocket, Icarus, lasting about five seconds. We intend to launch Icarus at the Friends of Amateur Rocketry site at the earliest possible opportunity.

Thank you to @Elegoo_Official for providing BURPG with a Saturn 4 Ultra 3D Printer and Mercury X Bundle. This printer will be used for our Hybrid Intro Project which aims to teach all members of the BU community about the basics of rocketry.

As BURPG begins a new year let's recap on last year's accomplishmnets: 1 designed, manufactured, and tested 2,500 lbf bipropellant rocket 4 cold flows of both nitrous oxide and IPA 1 24 ft I-beam established for our testing infrastructure 2 revisions of our flight computer

@kegrocket @lightingmatt Immensely complex and high risk.

@lightingmatt @BURPG 💯 We are prepared to place an order for two drum boosters

.@kegrocket IPA Can boosters? (@BURPG dictator for scale)

There was no damage to hardware, and all signs point to an isolated issue with the particular igniter used for that test. The team intends to continue the test campaign at the earliest opportunity. (2/2)

On Saturday, BURPG made two hotfire attempts. The first was successful, but shutdown somewhat early due to lower than expected oxidizer density. After making procedural changes to extend the burn, the team recycled and fired again. This resulted in a minor hard start. (1/2)

Yesterday afternoon, BURPG conducted a 1 second hotfire test—the first by the team in several years, and the first ever on the Horizontal Test Stand. Initial data review indicates that all performance targets were met, with 2,500 pounds of thrust. BURPG.org

January 2023 Cold Flows: Over the last several weeks, BURPG has conducted a number of additional fuel and ox cold flow tests. The team has reviewed the data, closed out all open items, and intends to step into hot fire attempts in the near future. burpg.org

BURPG conducted several tests of our Horizontal Test Stand’s oxidizer systems on Saturday, culminating in 2 cold flow tests consuming a combined 100 lbm of propellant. This provides invaluable data as we prepare for acceptance testing of our flight engines burpg.org

BURPG is partnering with @bu_spark to support their Resiliency Challenge: a nine-week virtual hackathon aimed at helping colleges and communities cope with the COVID-19 crisis. If you want to join a hackathon team, you can learn more and sign up here: theresiliencychallenge.io

Had a fantastic “hack”-a-thon today where our teams spent a marathon of a day collaborating on our two huge projects. Over thirty people came to make tons of progress! Some serious history in the making. Announcements coming very soon

Manufacturing of Mortise, our 450 lbf Methane Gox rocket engine, has been concluded. Nitrogen flows, cold flows, and hot fire upcoming. Designed by: Justin Fiaschetti Adam Kotler Carla Sheridan

Relativity goes to college -- we were with the @BURPG (Boston University Rocket Propulsion Group) a few weeks ago -- they totally blew us away. It was absolutely impressive to see what these students are doing.

Huge thanks to McArthur High School for visiting and letting us talk about what we love. Had a great time meeting the students and inspiring the next generation of BURPG engineers!

@yorkatmars It is for our RCS to control the roll of the rocket.

@BURPG Wondering what's that nozzle for?

We are very excited to announce that we will be launching our Low Althitude Demonstrator rocket (LAD) this summer in Black Rock Nevada! Over the past two year we have designed, built, and tested all components of LAD. More info coming soon. #PathToSpace
