Giant iceberg off the coast of Antarctica.
Rockets look pretty impressive. Huge plumes of smoke and flame billow out of their base, while much further up, their tops, so slowly then oh so quickly, ascend into the heavens. Over in a few moments, the awe inspiring launches are the cumulation of years of analysis and design. Alfred J. Zaehringer and Steve Whitfield in their book give an insight into some of the more basic design elements. Their perspective, as it were, is literally 'from the trenches' as Zaehringer defended against the V2 rockets of World War II and then went on to assist with the up-rating of the Saturn C5 and the assessment of solid rocket systems. The result is a concise, yet broad overview of rocketry.
Jean-Jacques Dordain, the Director General of the European Space Agency and Anatoly Perminov, the Head of the Russian Federal Space Agency have signed an agreement that will promote cooperation and partnership in the development of new launch systems. The two agencies are already working together to build and launch Soyuz rockets from the ESA's spaceport in French Guiana. They now plan to begin developing a new launcher with reusable liquid engines and upper stages. They hope to have their new rockets flying by 2020.
B-15A is a giant iceberg off the coast of Antarctica, and it's now on a collision course with a floating pier of ice called the Drygalski ice tongue. satellite photos showed B-15A rushing towards the tongue, but then it slowed down in the last couple of days. scientists think that there's a shallow seabed underneath the Drygalski ice tongue that has protected it from these kinds of collisions for so long - it's been there for at least 4000 years. B-15A is 120 km (75 miles) long, and contains about 2000 square km (772 sq miles), so it just have the momentum to do the trick.
