The United Launch Alliance Delta IV Heavy rocket reached another major milestone on the road to T-Zero, as NASA's Parker Solar Probe is prepared for launch.
All is ready for launch of a United Launch Alliance Delta IV Heavy rocket carrying NASA's Parker Solar Probe. Liftoff is scheduled for 3:31 a.m. EDT from Space Launch Complex 37 at Cape Canaveral Air Force Station.
Hello, and welcome back to our coverage of the Parker Solar Probe launch. Everything is proceeding toward launch of the pioneering spacecraft at 3:31 a.m. EDT on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida. The weather forecast has improved to 95 …
The launch of a United Launch Alliance Delta IV Heavy rocket carrying the Parker Solar Probe spacecraft was scrubbed today due to a violation of a launch limit, resulting in a hold. There was not enough time remaining in the window to recycle.
The Parker Solar Probe countdown is underway toward a liftoff at 4:28 a.m. EDT. During the last four minutes of the countdown, the Delta IV Heavy propellant tanks will be brought up to flight pressure, the rocket and spacecraft will be confirmed on internal power, and the Eastern Range and launch managers will perform final status checks. A computerized autosequencer will take over the countdown in order to conduct a host of activities in precise order.
The launch countdown is in a T-4 minute hold. The launch team is proceeding toward launch of a United Launch Alliance Delta IV Heavy rocket carrying Parker Solar Probe on a mission to the Sun. Liftoff is now scheduled for 4:28 a.m. EDT with a 95 percent chance for favorable weather.
The rocket standing on the pad at Space Launch Complex 37 is a United Launch Alliance Delta IV Heavy configuration. The 233-foot-tall rocket is the world's second highest-capacity rocket and most powerful rocket currently used by NASA. The launch vehicle consists of three Common Booster Cores, each with an RS-68A engine. Each engine produces 702,000 pounds of thrust for a combined total liftoff thrust of more than 2.1 million pounds.
NASA's Parker Solar Probe will revolutionize our understanding of the Sun, our closest star. The spacecraft will use seven Venus flybys and 24 orbits over nearly seven years to gradually reduce its orbit around the Sun. The spacecraft will come close to 4 percent of the distance from the Sun to the Earth, and closer to the Sun's surface than any spacecraft before it.
The spacecraft will fly into part of the Sun's atmosphere, known as the corona, for the first time. The spacecraft will use four instrument suites designed to study electric and magnetic fields, plasma, and energetic particles, as well as image the solar wind. The mission will trace how energy moves through the solar corona and explore what accelerates the solar wind and solar energetic particles, enabling critical contributions to our ability to forecast changes in Earth's space environment that impact life and technology on our planet.
Good morning from NASA’s Kennedy Space Center in Florida. A United Launch Alliance Delta IV Heavy rocket stands ready for liftoff at Space Launch Complex 37 at Cape Canaveral Air Force Station. The Delta IV will launch NASA’s Parker Solar Probe on its journey to the Sun, venturing closer than any spacecraft before it. Launch is targeted for 3:53 a.m. EDT.
