Boeing Given $28B to Build World's Most Powerful Rocket
NASA recently finalized a $2.8 billion contract with Boeing to build the most powerful rocket to date, which will use four space shuttle engines and two solid rocket boosters to propel astronauts to Earth’s orbit and beyond. Boeing will build the rocket’s core stage, which will house the hundreds of metric tons of liquid hydrogen and oxygen needed to fuel the four main engines.
A test flight of the Space Launch System (SLS) has been planned for 2017. The test will demonstrate an initial 70-metric ton lift capacity configuration of the rocket that would carry an Orion spacecraft (without crew) beyond low-Earth orbit. The Register reports that a successful test would pave the way for the rocket to evolve into history’s most powerful launch vehicle with a lift capability of 130 metric tons. The rocket could potentially enable humans to embark on missions to near-Earth asteroids, the moon and Mars.
In a press release, vice president and program manager of Boeing SLS Virginia Barnes stated “Our teams have dedicated themselves to ensuring that the SLS—the largest ever—will be built safely, affordably and on time. We are passionate about NASA’s mission to explore deep space. It’s a very personal mission, as well as a national mandate.”
The SLS represents NASA’s first deep-space exploration vehicle for human missions since the Saturn V rocket took U.S. astronauts to the moon more than 40 years ago. The initial 70 metric ton configuration of SLS will have ten percent more thrust than the Saturn V. Upon the completion of the 130 metric ton configuration, it will provide 20 percent more thrust than the Saturn V. That configuration should provide the power necessary to complete human missions to Mars.
NASA’s legacy technology has been put to good use in the design of the SLS, including the incorporation of the highly efficient RS-25 engines used by the space shuttle. The SLS rocket will also use larger versions of the space shuttle’s twin solid-fuel boosters. The Orion spacecraft that will carry astronauts on their missions is inherited from NASA’s previous Constellation program, aimed at returning U.S. astronauts to the moon.
The deal makes Boeing the prime contractor responsible for the rocket’s core stage. At a height of 64.6 meters, the core stage will store the liquid hydrogen fuel and liquid oxygen oxidizer at cryogenic temperatures below -150 degrees Celsius. It will also house the rocket’s main electronic systems and flight computer.
Boeing faces the task of studying the upper stage required for the 130 metric ton version of the rocket. The upper stage would provide the boost necessary to send astronauts on deep space missions. Pratt & Whitney Rocketdyne is currently developing two J-2X engines for upper stage use that would be fueled by liquid hydrogen and oxygen.
NASA and Boeing representatives recently met as part of the Critical Design Review (CDR) board overseeing the SLS at NASA’s Marshall Space Flight Center in Huntsville, Alabama. This was the last major review before production began on the core stage.
“Completing the CDR is a huge accomplishment, as this is the first time a stage of a major NASA launch vehicle has passed a critical design review since the 1970s,” Tony Lavoie, manager of the Stages Office at NASA's Marshall Space Flight Center, said in a press release. “In just 18 months since the Preliminary Design Review, we are ready to go forward from design to qualification production of flight hardware.”
With the Constellation program’s cancellation in 2010 and the subsequent retirement of the space shuttle fleet in 2011, NASA’s human spaceflight program hasn’t had much to celebrate over the past few years. But if NASA’s budget and test launch schedule stays on track, the 130 metric ton configuration of the SLS could ultimately blast off in 2021 with the Orion spacecraft and up to four U.S. astronauts in tow.
IMF: Variants Can Still Hurt Manufacturing Recovery
After a year of on-and-off manufacturing in the US, UK, and the eurozone, demand for goods surged early last week. Factories set growth records in April and May, suppliers started to recover, and US crude hit its highest price point since pre-COVID. As vaccination efforts immunise much of the US and UK populations, manufacturers are now able to fully ramp up their supply chains. In fact, GDP growth could approach double-digits by 2022.
Now, the ISM productivity measure has surpassed the 50-point mark that separates industry expansion from contraction. Since U.S. president Biden passed his US$1.9tn stimulus package and the UK purchasing managers index (PMI) increased to 65.6, both sides of the Atlantic are facing a much-welcomed manufacturing recovery.
Lingering Concerns Over COVID
Even as Spain, France, Italy, and Germany race to catch up, and mining companies pushed the FTSE 100 index of list shares to a monthly high of 7,129, some say that UK and US markets still suffer from a lack of confidence in raw material supplies. Yes, the Dow Jones has made up its 19,173-point crash of March 2020, and MSCI’s global stock index is at an all-time high.
Yet manufacturers around the world realise that these wins will be short-lived until pandemic supply chain bottlenecks are solved. If we keep the status quo, consumers will pay the price. In April, inflation in Germany reached 2.4%, and across the EU’s 19 member countries, overall prices have increased at an unusual pace. Some ask: Is this true recovery?
IMF: Current Boom Could Falter
Even as Elon Musk tweeted about chip shortages forcing Tesla to raise its prices, UK mining demand skyrocketed; housing markets lifted; and the pound sterling gained value. The International Monetary Fund (IMF), however, cautioned that manufacturing recovery won’t last long if COVID mutates into forms our vaccinations can’t touch. Kristalina Georgieva, Washington’s IMF director, noted that fewer than 1% of African citizens have been vaccinated: “Worldwide access to vaccines offers the best hope for stopping the coronavirus pandemic, saving lives, and securing a broad-based economic recovery”.
Across the globe, manufacturing companies are keeping a watchful eye on new developments in the spread of COVID. Though US FDA officials don’t think we’ll have to “start at square one” with new vaccines, the March 2021 World Economic Outlook states that “high uncertainty” surrounds the projected 6% global growth. Continued manufacturing success will in large part depend on “the path of the pandemic, the effectiveness of policy support, and the evolution of financial conditions”.
Mathias Cormann, secretary-general of the Organisation for Economic Co-Operation and Development (OECD) concurred—without global immunisation, the estimated economic boom expected by 2025 could go kaput. “We need to...pursue an all-out effort to reach the entire world population”, Australia’s finance minister added. US$50bn to end COVID across the world, they imply, is a small investment to restart our economies.
