U.S. stocks pull back from record highs as Middle East tensions push oil above $100/barrel.
Conflict around Iran and the Strait of Hormuz continues to unsettle energy and risk assets.
NASA’s Artemis II Moon flyby stands out as a major 2026 U.S. science and prestige milestone.
A study projects the Atlantic overturning circulation could weaken by up to ~58% by 2100.
Rocket Lab targets an Electron launch carrying NASA’s LOXSAT cryogenic test mission.
Markets & Economy
Markets Slip From Record Highs as Oil Surge Weighs
U.S. equity futures are lower this morning after the S&P 500 closed at a record on Wednesday, leaving the index up more than 9% for April. The pullback comes as investors reassess risks from elevated energy prices and geopolitical uncertainty.
Brent crude is trading above $100 per barrel, around $102–103, amid supply concerns tied to tensions around the Strait of Hormuz.
Prediction and derivatives markets are leaning toward a weaker S&P 500 open following Wednesday’s record close.
Higher oil prices and ongoing trade policy noise are reinforcing expectations that interest rates could remain elevated for longer.
Middle East Conflict Keeps Energy and Risk Assets on Edge
The unresolved conflict involving Iran and regional powers continues to disrupt sentiment in global markets. Threats around the Strait of Hormuz and warnings from Iranian negotiators about unspecified “new cards” on the battlefield are contributing to oil’s surge and episodes of volatility across risk assets.

Space & Science
Artemis II Marks Major U.S. Spaceflight Milestone
NASA’s Artemis II mission, flown earlier this month, sent its crew farther from Earth than any humans in history. The spacecraft looped around the far side of the Moon, surpassing Apollo-era distance records and cementing Artemis II as one of 2026’s defining achievements in science and technology and a significant marker of U.S. spaceflight prestige.

Study Warns of Significant Weakening in Atlantic Circulation
New research published in Science Advances projects that the Atlantic Meridional Overturning Circulation (AMOC) could weaken by roughly 42–58% by 2100. This is substantially larger than many earlier estimates and raises the probability of a long-term collapse.
A major slowdown in the AMOC would have far-reaching consequences for weather patterns in North America and Europe, with implications for climate risk assessments through the end of the century.

Technology & Space Infrastructure
Smart Materials and Orbital Fuel Depots Advance
Light-Responsive “Smart” Crystals
Researchers have demonstrated crystals that bend and snap back when triggered by light. These light-responsive materials are part of broader work on smart materials with potential applications such as micro-actuators and soft robotics.
Rocket Lab Electron Launch with NASA LOXSAT
Rocket Lab’s Electron rocket is scheduled for, or conducting, a multi-satellite launch today from Mahia, New Zealand. The manifest includes NASA’s LOXSAT mission, aimed at testing cryogenic fluid management in orbit. Data from LOXSAT are expected to inform development of a planned orbital “Cryo-Dock” propellant depot later in the decade.

Macro & Policy
Inflation and Rate-Cut Hopes Reassessed
The sharp rise in energy prices linked to the Iran-related conflict has complicated the previously improving disinflation backdrop. Commentary from major asset managers notes that markets have shifted from expecting multiple Federal Reserve rate cuts in 2026 to assigning greater odds that policy rates will stay elevated, or even rise modestly, if oil prices remain high.
