f9r flight test 1000m

video of falcon 9 reusable f9r taking its second test flight at our rocket development facility f9r quadrupled its height from its previous test to rise to 1000m early flights of f9r will take off with legs fixed in the down position however we will soon be transitioning to liftoff with legs stowed against the side of the rocket and then extending them just before landing the f9r testing program is the next step towards reusability following completion of the grasshopper program last year future testing including that in new mexico will be conducted using the first stage of a f9r as shown here which is essentially a falcon 9 v11 first stage with legs f9r test flights in new mexico will allow us to test at higher altitudes than we are permitted for at our test site in texas to do more with unpowered guidance and to prove out landing cases that are more-flight like
